The term “ferrous” refers to materials that contain or are derived from iron. In plumbing and construction, ferrous materials include iron-based components such as cast iron, steel, and wrought iron. These materials are commonly used in pipes, fittings, valves, and structural elements due to their strength, durability, and resistance to high pressure. However, ferrous materials are prone to corrosion when exposed to moisture, oxygen, or certain chemicals, necessitating protective coatings, treatments, or the use of non-ferrous alternatives in specific environments. Understanding the properties and limitations of ferrous materials is crucial for selecting the right components in plumbing systems, ensuring longevity and reducing maintenance costs.
